We didn't quite expect this video to become an Internet sensation when we posted it earlier this week, but goodness gracious do people love pantomimed blowjobs. At the time we called culprit Julian Dalrymple a "jackass," though it turns out he's actually a pretty nice guy who has a penchant for attention-whoring.

Julian's here to explain why and how he pulled the stunt, what drives a person to do such a thing, what it was like to be ejected by Wrigley Field security, and take whatever questions you have. Ask away.

Update (3:00 p.m.): The discussion is closed. Thanks to Julian for being a good sport.
